SPECIFICATION forming part of Letters Patent No. 436,971, datedSeptember 23, 1.890.

Application filed May 19,1890. Serial No. 352,314. (No model.)

To all whom it may concern:

Be it known that we, FOWLER IV. EMONS and CLEMENT B. BISHOP, bothcitizens of the United States, and residents of Philadelphia,Pennsylvania, have invented certain Improvements in Eyeglasses, of whichthe following is a specification.

Our invention relates to that class of eyeglasses in which thenose-pieces are sup- IO ported so as to be free to move both at top andbottom to accommodate themselves to the nose, the object of ourinvention being to so construct the supporting and retaining devices forthe nose-pieces that the latter will have perfect freedom of movementfrom and toward the nose, and yet will be properly retained in otherdirections, the device, more over, being of simple and economicalconstruction.

In the accompanying drawings, Figure 1 is an enlarged view, partly insection, of a pair of eyeglasses constructed in accordance with ourinvention; and Fig. 2 is a perspective View of part of the same.

A A represent the usual lens frames of the eyeglasses, which areconnected by a spring B, secured to studs a on the frames A, in theusual manner; .also secured to each stud a is a bent lug b, projectingupward and inward 0 from the stud, and this lug is slotted for thereception of the hooked upper end 01 of the nose-piece bar D, whichcarries the usual pad f, and is likewise hooked at its lower end d foradaptation to a slotted lug g on the lens- 3 5 frame A.

Confined to each of the studs a are a pair of springs m and n, thelatter being longer than the spring m, and both springs bearing againstthe nose-piece bar D, so as to push 0 the same outward to the full limitpermitted by contact of the hooked ends of the bar with the slotted lugsb and c, the lower end of the spring at being slotted so as to embracethe bar D, and thus serve to vertically support the nose-piece. It willbe observed that, ow-

ing to this construction, the nose-piece is not only free to move bodilyfrom and toward the lens-frame; but it can also yield independently attop and bottom, for the nose-piece is supported wholly by the spring a,the slotted lugs 17 and 9 simply serving to restrict the outwardmovement. If desired,the spring 12 may be riveted to the bar D at thelower end; but the construction shown is preferred, as a single screw ateach stud a is then all that is necessary in order to hold the partstogether. The spring n only may be used, if desired, for eachnose-piece, although the use of two springs is preferred,because of themore uniform action of the same upon the nose-piece, and the lugs 17may, if, desired, be continuations of the spring B.

By using nose-piece springs independent of the spring B the character ofsaid springs may be adapted to the special duty which they have toperform, whereas, when the nosepieces are acted upon by extensions ofthe bridge-spring, the stiffness of the latter is, in many cases,disproportionate to the work of supporting and projecting thenose-pieces.

Having thus described our invention, we claim and desire to secure byLetters Patent 1. The combination of the lens-frames and theirconnecting-spring, the nose-piece bars having hooked ends, slotted lugson the frames 7 5 for retaining said hooked ends, and supporting-springsacting on the backs of the nosepieces to project the same, substantiallyas specified.

2. The combination of the lens-frames and the connecting-spring, thenose-pieces having hooked ends, supporting-springs, and a supplementaryprojecting spring for each nosepiece, and slotted lugs serving asretainers for the hooked ends of the nose-piece bars, substantially asspecified.

3. The combination of the lens-frames, the connecting spring, the nosepieces having hooked bars, slotted lugs serving as stops for said hookedbars, and springs engaging with the lower portions of the nose-piecebars and serving both to project and support the same, substantially asspecified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
